Umut ISIK: I created a hello world vaadin project name Test1. When i tried compile vaadin widgets i have same problem. I tried to change web.xml to

<servlet-mapping>
    <servlet-name>Vaadin_test Application</servlet-name>
    <url-pattern>/VAADIN/*</url-pattern>
 </servlet-mapping>

This setting in web.xml only affects execution, not GWT compilation.

If you map /VAADIN/*, you also need to map your application to the same servlet. Alternatively, you can just map /* to your servlet - that way, also requests to /VAADIN/* go to your servlet.

Ubuntu 12.04 LTS
JDK 1.7.0
Eclipse Indigo
Vaadin Plug-in 2.0.1
vaadin-6.7.6.jar

I don't recall having seen this before. I would recommend checking if using Oracle JDK 1.6 for widgetset compilation helps. Widgetsets are compiled by the plug-in with the project or workspace JDK as long as it meets minimum requirements for the GWT version used, so you can change the project JDK to point to a JDK 1.6 installation and retry compiling the widgetset.
